A customer hands you a package to ship and you notice the destination address appears incorrect or incomplete. What's the BEST action?

Address issues cause delivery problems — undeliverable mail, returns, delays, lost mail. Catching them at intake is much better than discovering them in transit. The exam is screening for: (1) NOTICING the issue — attention to detail at intake; (2) RESPECTFUL communication — don't lecture or imply the customer is careless; (3) HELP CORRECT — assist looking up zip codes, suggest checking for missing apartment numbers or street types, etc.; (4) VERIFY before processing — ship only when address is complete and correct. Just shipping anyway creates delivery problems for the customer and additional handling cost for USPS. Refusing to ship is excessive — most address issues are fixable in the moment. Making up an address is fraud and would misdeliver private mail. The right pattern: notice + respectful pointing-out + help correct + verify before processing. Customers appreciate clerks who catch issues at intake — it saves them from having a package returned.
